That's interesting...
Looking at the domain index page for
http://www.adultxxxdomains.com/ if you check the google cache copy it shows the index page for:
http://www.caribbean-poker-stud.com/
That seems like the sort of thing you see when you use se cloaking!
I'm no expert in this area... just wondering if it's connected to that casino script you are using:
<SCRIPT language=JavaScript1.1
src="http://affiliate.casinorewards.com/members/affiliate/exit_code_js.asp?aff_id=aff17615&casino_id=3"></SCRIPT>
<!--End Affiliate CasinoRewards Exit Code -->
I checked their site but they make no mention of any traffic exchange type program or anything like that...
Maybe it's just a mess up at google!
I'll be most interested to hear your thoughts DD.
